Thanks for the feedback everyone!
@Nighthunter - I'll draw some RDCAF variants up for you when I do the export versions
@Blackbuck - I've had a look at some aircraft of similar power and era and some have a contra-prop and some don't, but there is a lot of sense in the suggestion. I'll have a go at drawing one up but I'm thinking at this stage it will probably stay as a prototype for a cancelled improved version rather than reach full-time squadrons.
